Highland cattle originated in the Highlands and Western Isles of Scotland and were first mentioned in the 6th c. AD.
They have long horns and long wavy coats that are coloured black, brindle, red, yellow, white, silver (looks white but with a black nose) or dun, and they are raised primarily for their meat.
The first herd book described two distinct types of Highland cattle but, due to crossbreeding between the two, only one type now exists and is registered. They have since been exported worldwide.
They are a hardy breed due to their native environment, the Highlands of Scotland.
This results in long hair, giving the breed its ability to overwinter.
